Overall this is very nice!

Please do not use these custom enumerators 1 thru 7.
Instead say that the argument is given in ohms, so for
example:

bias-pull-up = <12000>;

Then translate this into the proper enumerator in your
driver instead.

No full example provided in the binding! This needs to
be there for understanding.
